Hynix ufs has deviations on hi36xx platform which will result inufs bursts transfer failures.

To fix the problem, the Hynix device must set the registerVS_DebugSaveConfigTime to 0x10, which will set time referencefor SaveConfigTime is 250 ns. The time reference for SaveConfigTimeis 40 ns by default.

This patch is necessary to boot on HiKey960 boards that useHynix UFS chips (H28U62301AMR model: hB8aL1).
